A compound is found to contain 59.94% carbon 13.44% hydrogen and 26.62% oxygen by mass

C3H8O

Explanation:

These are the steps:

1. Write the given value for each element.

2. divide them by their Ar.

3. Divide the result by the smallest value in the ratio.

C H O 59.94% 13.44% 26.62% 59.94÷12 13.44÷1 26.62÷16

4.995 13.44 1.664

(4.995÷ 1.664) (13.44÷ 1.664) (1.664÷1.664)

3.00 8.07 1

3 : 8 : 1

So the compound is C3H8O.
